In the swaging process, tubes cannot be swaged without the application

1.	In the swaging process, tubes cannot be swaged without the application of mandrels.(a) True(b) FalseI have been asked this question by my college professor while I was bunking the class.I'd like to ask this question from Swaging in chapter Miscellaneous Forming Processes of Casting-Forming-Welding II
Answer» Right answer is (b) False For explanation I would say: In the swaging process, tubes can be swaged with or without the application of mandrels. In the case of swaging without mandrels, the surface finish obtained will not be proper and ACCURATE when a blow is APPLIED onto the material during the operation. When the length and THICKNESS of the material increases simultaneously, then the need of MANDREL becomes essential.
